DAVID TRUE, OF AMESBURY, MASSAUI'IUSETTS,

' OIL-CAN.-

srncrrrcn'rron forming e rea -raters No. 553,726, dated January 28, 1896.

Application filed April 25, 1896.

To all whom it may concern:

' Be it known that 1, DAVID TRUE, a citizen of the United States, residing at Amesbury, in the county of Essex and State of Massa' chusetts, have invented new and useful Improvements in Oil-Cans, of which the following is a specification.

This invention relates to that class of oilcans in which a pump is employed for driving the oil through the discharge-spout; and the invention relates to the-means whereby distant and elevated bearings-such as are found in shafting, for example-may be reached, to the construction whereby the can may be easily carried from one point to'another by a single hand and the pump operated by the same hand, and to certain details in arrangement and construction, all substantially as illustrated in the accompanying drawings, in

which-- Figure lis an elevation of my improved oilcan, a portion; being shown in vertical section and parts of the mast and connecting-tube being represented as broken out. Fig. 2 is a with the connecting-tube broken off. Fig.3. is a central vertical section of the same.

Similar letters of reference indicatecorrespending-parts. 3o A represents a reservoir or fou-nt, made of any suitable material and provided with an opening a, by-means of which it may be, filled, and a cap a for 'closingsaid opening.

B is a plug which sits snugly in the can and is formed to rest uponthe upper edge b of the mouth, andto be detachably secured thereto by a suitable fastening contrivance A"; This plug is provided with a central bore B" which is counterbored and screw-threaded 4o at B' to receive the small plug 0, which is -centrally and vertically bored to receive the piston-rod D, which moves through suitable packing 0', supported by a centrally-perfo rated disk or washer O", which lies between the lower edge of the plug (1 and the 'ledge' produced by the counterbo'r'ing of the passage B". The piston-rod- D' is'provided near its lower; end with the piston D, provided with suitable radial openings d, said piston fitting. 5c and moving-vertically in a tube B, which extends down from the plug B toward the bottom of the can; A spring e surrounds the plan view of'the same without the mast and the rigid tube H.

piston-rod andextends from the washer C" to a cross-piece or support'e secured to the pis ton-rod, as shown in Fig. 3, and a sliding-valve D, of less diameter than the piston, moves. on the rod D between the piston and the crosspiece 2'. To the upper end of the piston-rod is secured alifting=ba'r, consisting of thecentral portion E and cross-piece E, the latter having. its under side formed into finger-recesses E", as shown. A- passage F leads on an upward incline from the passage B to the outer side of the plug 13, such passage being lessened in diameter at its inner end to retain a ball-valve 1?, whose upper or outer movement is limited by the screw F. Thus the lower end of the passage is closed by gravity'and air prevented from entering the passage B" when the oil-can is not in use. Thus far there is nothing described which is claimed to be new inthis invention. The

piston-rod is lifted by raising the finger-bar E E and the oil pumped from the can through the tube B and passages B" F into the connection leading to the nozzle, below described.

f isa rigid pipe screwed into the outer end of. the passage F, and attached to the outer end of this pipe is one end of the flexible tube H, whose outer endis attached to one end of The upper end of the tube H' has the lower end of aflexible tube 71/ secured to it, and the other end'of the flexible tube 71/ is secured to-the rear end of the nozzle h. This nozzle is pivoted at h on a socket or cap J mounted on or inclosing the upper end of a mast J, to which the rigid tube H is secured'bythe bands J. (See. Fig. l.) Y

The nozzle being pivoted and its. rear end secured to a flexible tube,'it can accommodate itself to any position by pressure and proper direction of the mast. The flexible connection H is long enough to allow of suflicient freedom of movement of the mast with relation to the can. 7

N is a drainage-passage extending from the passage F down through the plug B and openupper endof the rod P',"and said lever'is fulcrumed at r on the bracket 7'', secured to the upper surface of the plug B. The .forward end of the lever B is provided with'a slot R,

"Fig. 2, and through this slot projects a spring S, set vertically in the upper surface of the plug B, and provided with a notchS'. I

When it is desired to empty'the nozzle and connecting-tubes h HT H of any oilwliich may be in them, as would be the case after such bearings as needed attention had, been-supplied with oil, the front end of the lever B is lifted until it reaches the notch S, when the outwardly-pressing spring S brings said notch under the edge of the slot R in said lever,

and the lever is supported in a raised position.

The raising of the front end of the lever pushes down the rod P'-and lowers the valve P, thus allowing the oil to pass from the nozzle and pipes 'h, H and H through the connection f into the inclined passage F," and thence through thevertical passage N into the reservoir or can. It vwill be seen that this drainage-valve is especially useful when elevated spouts are employed, not only because of the amount of oil which is necessarily in the tubes between the spout and the reservoir, andwhichwould run out and'be lostas soon as the spoutis lowered, but also because the flexible tubes which make parts of the connection are necessarily distended and can by this method be relieved. As soon as the oil has returned to the reservoir, a rearward pressure on the spring S relieves the lever B, and the valve P returns (by means of the spring 'n) to its normally-closed-position. Y

In carrying the spout from onebearing to another it is advisable to lift the catch a little in order to allow enough oil. to B back to At the same time the lower end of the prevent any dripping. One end of the-lifting-bar E is turned up a little at E, and is furnished at that point with a small depression E"". This is for the accommodation of the thumb while the forefinger (or other fin ger) is employed in lifting the lever It. (See broken lines in Fig. 1.) The palm of the hand beingon the rest K andthe fingers be' ing undertlfe' fin ger-bar E, when one finger is removed from the finger-bar for the purposeof pressing up the) lever B, the pressure of the thumb upon the finger-bar is advisable and almost necessary, not only in order to steady the device, but also to prevent involuntary lifting of the finger-bar.

A socket T is provided for the mast I.

This application is made concurrently with another application by me for an improvement in oil-cans, Serial No. 547,07 9, in which the'construction of thelca'n A, plug B,'and pumping mechanism are substantially the same as in this application. These parts are not: claimed therefore in' this application in themselves considered.
